Provider hosted app error message: The remote server returned an error: (429) Too Many Requests.

Hi,
I have a customer running a provider hosted app and in Sharepoint 2013. Things have been working fine but recently they keep experiencing an issue where the all the app parts on the page show the following error message. Does anyone have an idea what
could be causing this problem and how I can fix it? The Sharepoint site and provider hosted app site are running on a Server 2008 R2 box with IIS 7.5.
Server Error in '/Test.Sharepoint.App' Application.

Hi GuYumming,
I have checked the Sharepoint site using Fiddler and my X-SharePointHealthScore stays consistently on 1, I have even refreshed the site and had the "(429) Too Many Requests" error happen right in front of me whilst Fiddler is running and when I look at the
200 response for the Sharepoint site it is still showing "X-SharePointHealthScore: 1".
I assume because of this I do not need to make any of the changes suggested in your article above?
I have also been through the ULS logs and found the following 3 log entries that appear to relate to the issue but they do not really mean much to me so I am hoping that you can help:
Begin CSOM Request ManagedThreadId=59, NativeThreadId=12476

Hi Harminder,
This happens because an app has already been deployed and you are deploying it again using the same version.
Resolution:
Open the AppManifest.xml file and change the version.

The remote server returned an error: (404) Not Found.

Hi All
Now I try to deploy my SAP Portal Project it gives following error message "The remote server returned an error: (404) Not Found.". What is missing?
Regards

Hi,
In order to check if those seetings are ok, do following:
Open internet explorer (or another) browser and go to
http://localhost:50000/irj
You should get the Portal homepage with login screen.
If you don't - then you have a problem with your local portal ( may be it is not running ).
If you do - Login with username: administrator and
password: abcd1234
If you don't succeed to login, then you have a problem with your user( may be it does not exist ).

I have created one web
job - on demand schedule under azure web site. This web jobs contains .execmd(i.e.)

I am retrieving the data from SQL Azure database and uploaded the data in sharepoint online lists. (i.e.)I have uploaded the data to several(7) lists in each subsites. I have 3 subsites.
I am getting this error "The remote server returned an error 503 server unavailable", while uploaded the data into lists.

Totally 4 hours taken uploaded the data into list for completed all 3 subsites.
If anyone know how to resolve this.
Thanks,

Hi,
Per my understanding, there is an issue when uploading data from SQL Azure database to a SharePoint list in Online environment.
For narrowing down the issue, I suggest you create a Console Application in Visual Studio without accessing the SQL Azure database and upload some sample data to the same SharePoint
list to see if the issue still occurs intermittently.

Hi,
On a local server you don't have to change the web.config if you use local Windows Groups. Check if the User is added to the "BizTalk Server Administrators" Group. Also check if the Group or the User has rights to access EsbExceptionDb & ESBAdmin
database. You also have to enable "Windows Authentication" in IIS for the ESB.Portal.
Local Machine settings:
ESB.Exceptions.Service\Web.config
<connectionStrings><add providerName="System.Data.SqlClient" connectionString="Integrated Security=SSPI;Data Source=.;Initial Catalog=EsbExceptionDb" name="EsbExceptionDbConnectionString"/></connectionStrings>
C:\Projects\Microsoft.Practices.ESB\Source\Samples\Management Portal\ESB.Portal\Web.config
<connectionStrings>
<add name="AdminDatabaseServer" providerName="System.Data.SqlClient" connectionString="Network Library=dbmssocn;Data Source=(local);Integrated Security=True;Initial Catalog=ESBAdmin;"/>
</connectionStrings>
<authentication mode="Windows"/>
<authorization><allow roles="BizTalk Application Users"/>
<allow roles="BizTalk Server Administrators"/>
<allow roles="Administrators"/>
<deny users="*"/>

Did you create a new web application or modify an existing web application?
I would start by checking the ULS logs, maybe there is an incorrect setting within one of the web.config files, or SQL permissions.
Also, as suggested above, check application pools are running.

but when im process file , then file try hit partner url goes dyhradated state,then failed. then i got below error.
The remote server returned an error: (500) Internal Server Error.
please any help..
Thanks

500 server error could be due to anyone of the following reasons:
Party configuration is wrong. Party properties/configurations have to be discussed upfront with the source/destination system and have to be in-line with
them.
Certificates have to be deployed in correct folders based on certificate types like private/public/signed etc.
Firewall (or network components) has to be opened accordingly for parties(systems) to interact. This change has to be done at the both the levels, source and destination.
If you receive it through HTTPReceive.dll (may uses this for AS2), you have to check its configurations.
Also 500 error, could occur even if your BizTalk artifacts has not been configured/deployed/enabled properly.

Provider-hosted Apps debug error: The remote server returned an error: (401) unauthorised

Hi,
Any help appreciated!!
I'm getting this error: "The remote server returned an error: (401) unauthorised when I debug a provider-hosted app. I get the error on this line:

I created a high trust development environment following the instructions provided here:
http://msdn.microsoft.com/en-us/library/office/fp179901(v=office.15).aspx and
http://msdn.microsoft.com/library/office/fp179923
I created a provider-hosted app with the intent to:
create a SharePoint list in the appweb
Use self-signed certificate, tokenhepler.cs and sharepointcontext.cs to retrieve current user context and access on SharePoint. (No changes were made to tokenhelper.cs and sharepointcontext.cs)
retrieve list items from the SharePoint list in a button click event handler on a default.aspx of the remote web
What happens:
The app is deployed successfully to the Dev site
The SharePoint feature is deployed and activated
The default.aspx page of the remote web loads
The error (see image) is returned on clicking of the button

Hi ,
Use the below code
Public string GetAccessToken(){
string sharePointSiteUrlHost = Page.Request["SPHostUrl"].Tostring();
string AccessToken = tokenHelper.GetS2SAccessTokenWithWindowsIdentity(sharePointSiteUrlHost, Request.LogonUserIdentity);
return accessToken;
Than initialize the ClientCOntext with the below Method
private static ClientContext GetClientContextWithAccessTokenString(string targetUrl, object accessToken)
ClientContext clientContext = new ClientContext(targetUrl);
clientContext.AuthenticationMode = ClientAuthenticationMode.Anonymous;
clientContext.FormDigestHandlingEnabled = false;
clientContext.ExecutingWebRequest +=
delegate(object oSender, WebRequestEventArgs webRequestEventArgs)
webRequestEventArgs.WebRequestExecutor.WebRequest.UserAgent = "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)";
webRequestEventArgs.WebRequestExecutor.RequestHeaders["Authorization"] =
"Bearer " + accessToken;
return clientContext;
use this clientCOntext and it will work.
Do not use

BizTalk to Web Service - Error - The remote server returned an error: (403) Forbidden.

Hi Everyone,
I am connecting to an external web service from my biztalk application through a dynamic send port.
When my biztalk application is trying to send the request message to the web service through the send port, I am getting the following error :
The remote server returned an error: (403) Forbidden.
The external web service team have provided a certificate and a private key to install in my server.
I have installed the certificate by double click the .pfx file using the private key and have added the certificate in the host ProcessHostx64.
Still i am getting the same error.
Can someone help on this issue ?
Many Thanks,
Anand
S B A

The Private Key should be installed under the user running the BizTalk Server Host. Please confirm that you have done this?
If so, try to make this work in a small .NET test Application before porting it to BizTalk, so that you can confirm that you do have sufficient credentials to call the Service.

Hi Mou,
I just tried your win app code about calling web service, but failed. I got the 500 error after I called your service:
The error message I quoted from Fiddler:
<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><soap:Fault><faultcode>soap:Client</faultcode><faultstring>System.Web.Services.Protocols.SoapException: Failed : Invalid credentials ---> System.Exception: Invalid credentials

I am not totally sure that error occurred by the authentication. But I suggest you can try to add this service into your project using this method below:
1.right click the Reference and select Add Service Reference
2.input your service link and click "Go"
And you can use this service as the following:

The remote server returned an error: (401) Unauthorized. IIS problem? (Beginner)

(Beginner) Creating a Provider-hosted calendar list programmatically.
I have done this:
Uri hostWeb = new Uri(Request.QueryString["SPHostUrl"]);
using (var clientContext = TokenHelper.GetS2SClientContextWithWindowsIdentity(hostWeb, Request.LogonUserIdentity))
Web web = clientContext.Web;
ListCreationInformation listCreator = new ListCreationInformation();
listCreator.Title = "CompanyCalendar";
listCreator.Description = "Workcalendar";
listCreator.TemplateType = (int)ListTemplateType.GanttTasks; //106 = events 120=CustomGrid 140=WorkflowHistory 150=GanttTasks
web.Lists.Add(listCreator);
clientContext.ExecuteQuery();
If I remove the code above there are no problems, as the title says there is something wrong with my permission to modify but I have set the wevb permission to "Full control" so it should be something else.
Some people thinks that it has to do with IIS so I tried to set the servers authorization rules to allow all users but that didnt do it (maybe I didn't do it right).
Im a beginner so please explain as you would for a absolute beginner that dont know IIS.How can I solv this problem, why doesent I get permission to create a list on my sharepointsite?
thanks

Hi ,
I was also facing the same issue on changing my credentials. This effects the ServiceTokenApplicationPool and other pools related to the Web applications
To resolve this follow these :
1. Open IIS Manager , under Connection section you can see the Name of your site collection(as
siteCollectionName(Username))
2. Open SiteCollection , select Application Pools. A new window with your Web application pool names would open.
3. Right click on web app, select Advance Setting... , under Process Model select Identity
4. check for Custom account , click set and enter your Credentials and click
OK
Atlast Refresh the IIS manager.
Thank you.
Under application pools Do select the ServiceTokenApplicationPool also and follow steps 3 and 4
